The `Schedule referred to in these Letters Patent and making part of the same.

' Beit known that I, J o HN I. Srmnwoon, of Fort Edward,.in the county of Wasl1ington,and State of New York,have invented a new and useful Improvement in Cylinder. vIaper-lVIachine; and I do hereby declare` that the followingis a full, clearfand exact description thereof, which will enable thosefskilled in the art to make and `use the same, reference being had to the accompanying drawings, forming` a part of this-specification. y Figurel is a topor planview of myiuiproved machine.'

lligure 2, is aver-tical longitudinal section ofthe same, taken through` theline a: @dgn-1. *l "Fignrepis a detail view ofthe regulating-gate. j Similar letters of referencelindicate corresponding parts.`

` inventionn has for its object toY improve the clonstructlon ot paper-machines, so as to make them more convenient-and effective in operation, and especially so"as to cross or interlaccthe fibres of the pulp, to "produce a paper equally-strong in every direction; and It consistsin the constructionl and combination of variousgpalts,,as-hereinafter more fully described.

A'is the vat,.,i nto which the paper-,pulp is placed,

Vandfrorniwhich it is'removed bythe cylinder or cyl- `inders'tg an ordinary `paper-machine'.

" -B is 'a partitiomzwhich separates the compartment `j a', into which the pulp is placed, from the* compartment orcoinpartments iuwhichthe cylinder or cylinders work.4

` Fromvthe compartmenta thepulp passes into lthe `cylinder-"compfax'tm,ent through openings in .the lower 4 part of thepaitition B, the size of 'wl'lichiopenings is i regulated by the sliding gate C, adjustably attached Y to the saidpartitionB, asshown in iig. 3

'Upon the lower parto'ffthe partition B are formed or to it are attached arms, b, pr`ojecting into the cylindercompartment, directly opposite the inductionopenings, andthe lower edges of which are bcvelled oti', sodthat, asthc pulp liio'ws in througli thesaid inl duction-openings, vit inay be divided bythe said arms into a number of lateralf` currents, the tendency of ,which-is' to cross or interlace the tibres lof the pulp.

D is the cylindenby which the pulp' is taken up,l

` and fromI which ,itis -transferredto the paper-machine'.

The journals of the cylinder work in bearings inthe 'sides ofthe yatA, and` iuotiou may be communicated to said `cylinder by means of apulley, E, 'att-ached'to one ot'said journals. 4

The ends of the cylinder D are notched or serrated in rsucli a way'that the depressions inthe one end may be'directly opposite the projections inthe other end, i

. as shown in ng. A1.

Fis aifaue, restingandslidiug in notches or grooves.. inthe upper-edges ofthe vat A, and to the ,end bars of which are adjnstably attached tongues, G, the inner projecting `ends of which are rounded off'to correspond v with the teeth' or notches in the ends'ofv the cylinder ID, so that; as the said cylinder isrevolved, the frame E may be moved back and forth, the amount of .movemeut being regulated by the adjustment of theton'gues i'rltfhe trame Flare attached the ends of bars or rods, H, vwhich may-be made round or flattened, and

. which are cn'rvedso as to pass around beneath the cylinder D, asshouwuing. 5?',4 so that, as the frame E F-is vibratedfthe rods'H, moving through the pulp,

may cross and interlace the f bres of they pulp, so that when taken up by the .cylinder D, they may cross each other, and be interlaced with each other in every direction, giving auniform texture and strength to th paper in every direction.

When the machine is made double, or is provided with a` second cylinder, I, for the manufacture of heavy jpapenthe partition J, that separates the two compartments-in whichvthe twocylinders D and. I work, is slotted horizontally near its upper edge, from which slot aseri'es of open spots or troughs, K, leads, which said spouts-are curved to pass beneath the cylinder I, andare -at the same time connected with the `frame Fso as to receive a lateral movement from said-frame F,"causin`g the'pulp-bres to cross and be interlaced with ,each other as they arebeing taken up by the said cylinder I.

. Having thus described rny invention,

,.lVhat 1I claim as new, and desire to secure by Letters Patent, is'- y l. v'lhe'arrns b', bevelled oii upon their lower. edges, in combination with the induction-openings through 'the partition B, substantially as herein shown and described, and -for the purpose set forth.

2. v.The combination of the sliding or vibrating frame F, and curved rods or bars H, whether round or lat-` tened, with the cylinder D, substantially as herein shown and described, and for the purpose set forth.

`3. Operating the sliding or `vibrating.- frame F by meanscf the tongues G adjustably attached to the said frame F, and the notches or teeth formed in or upon the ends of the cylinder D, substantially as herein shownl and described.

4. The 'series of curved spouts K, in combination with the cylinder I, slotted partition J, and sliding or vibrating frame F, substantially as herein shown and described, and for the purpose set fort-h.`

The above specification of myvinvention signed by me, this .3d day of July, 1868,.
